Features

  • Multi-TW peak-power pulses at up to 1 kHz
  • 800 nm, 1600 nm, or 2000 nm output
  • Few-cycle pulse duration and high pre-pulse contrast
  • Robust design with < 1-hour warm-up time
  • Exceptional CEP and pulse energy stability
  • Spectral-temporal pulse shaping options
  • Dual output option

Applications like high-energy attosecond pulse generation, generation of high harmonics from solid targets, and laser electron acceleration all benefit from few-cycle pulse durations and excellent pulse contrast while requiring multi-millijoule pulse energy. Our most powerful high-energy OPCPA systems are scalable to multi-TW peak powers at kHz repetition rates while maintaining few-cycle pulse durations. Thus, they fit the most demanding requirements while providing stability and reliability unprecedented for systems of this scale.

Furthermore, > 10¹² pre-pulse contrast is obtained without complex and lossy nonlinear pulse cleaning techniques, while < 250 mrad CEP stability and < 1.5% pulse energy stability are maintained throughout a full day of operation, making it a robust and reliable multi-TW system.

The LIGHT CONVERSION and EKSPLA consortium have built the SYLOS laser system at the ELI-ALPS facility. To our knowledge, the SYLOS laser system at 1 kHz repetition rate generated four times higher peak power pulses compared to the state-of-the-art systems at that time.

The SYLOS laser system is based on LIGHT CONVERSION’s optical parametric chirped-pulse amplifiers (OPCPAs) driven by our PHAROS femtosecond laser and EKSPLA’s picosecond laser. PHAROS pumps two femtosecond OPAs. The first OPA produces passively CEP stabilized pulse at 1.3 µm, which is used for generation of CEP-stable white-light continuum (WLC). At the same time, the second OPA amplifies the WLC in the 700 – 1000 nm spectral range, providing high-contrast seed pulse for the subsequent OPCPA stages. The pulse, amplified to 50 mJ pulse energy at 850 nm central wavelength, is compressed in a sequence of glass blocks and chirped mirrors down to 10 fs pulse duration.
